1 Optics Review 1. On a trip to BC, you take a picture of a redwood cedar which stands 75m tall. It is one of the largest trees in Canada. You stand 120 m away and the pinhole camera has a length of 45cm. Calculate the height of the image. 2. Calculate the image distance in a pinhole camera for the object that is 20 m away, 3 m high, and has an image height of 1.5 m. 3. An object is placed 50 cm away from a curved mirror. A virtual image appears 30 cm away from the mirror. Find the focal length and state what type of mirror this is. 4. Calculate the index of refraction for a diamond (v=1.25 x 10 8 m/s). 5. A 24.0 cm high object is placed 10.0 cm in front of a convex lens with a focal length of 18.0 cm. Calculate: a) the position of the image b) the height of the image 6. Continue the light beam in the diagram below as it travels from air (n=1.00) into glass (n= 1.52). Calculate all angles of incidence and refraction. Use proper ray diagram format and show all of your work. 7. Complete each of the following diagrams on a separate sheet of paper. a. Concave mirror f=3 cm object distance = 7 cm b. Concave mirror f = 3 cm object distance = 2 cm c. Convex mirror f = 3 cm object distance = 4 cm d. Convex lens f= 3 cm object distance = 5 cm e. Concave lens f=3cm object distance = 5 cm Be sure to: a) draw at least 2 rays for each diagram b) draw the image on your diagram. c) state the image characteristics

2 8. A convex lens with a focal length of 9.0 cm is used to produce an image of an object. The magnification of the image is Calculate the distance the object is from the lens, if the image is at 12 cm. 9. Complete the following plane mirror diagram 10. Label the following eye diagram and indicate the function of each part. 11. What is farsightedness? Where is the image formed for someone that is farsighted? What type of lens is used to correct farsightedness? What is the medical term used for farsightedness? 12. What is nearsightedness? Where is the image formed for someone that is nearsighted? What type of lens is used to correct nearsightedness? What is the medical term used for nearsightedness?
